About Carton Blanc
Carton Blanc is online software for invitations, registration and check-in at events by invitation, published by MAKEO SAS, whose registered office is in Boulogne-Billancourt, France.
What Carton Blanc is
Carton Blanc manages events by invitation, from the guest list to check-in. The organiser creates the event, imports guests, reads the prepared emails, receives registrations and checks arrivals off on a phone.
It is for associations, clubs, companies, galleries, wine houses and any organiser of dinners, galas, conferences or weddings.

A reference: Private Equity Valley

The partners of MAKEO, which publishes Carton Blanc, are also partners in Private Equity Valley.
“Carton Blanc was born from our own events. We needed a tool that sends well-made invitations, reminds only those who haven't replied, and sells nothing to our guests. We built it, then opened it to other organisers.” — Stéphane Molère
Where the data is held
The guest list and registrations are hosted in the European Union, in Paris. The organiser remains responsible for their list; Carton Blanc hosts it on their behalf, does not sell it, does not pass it on and does not use it for itself. The organiser can export it to Excel at any time.
Pricing
Carton Blanc costs €99 incl. VAT a month (€82.50 excl. VAT) with no commitment, or €990 incl. VAT a year (€825 excl. VAT). A single event costs €49 incl. VAT (€40.83 excl. VAT), paid once: its emails and page stay open until 30 days after its date.
What Carton Blanc does not do
Carton Blanc is not a ticketing tool: it takes no ticket payments. No email is sent without the organiser's approval. There is no advertising, no resale of data and no free plan.
